Remote relay beacon. Dellis Tantor plants a remote relay beacon. Remote relay beacons were tall communication structures which could retransmit data through a line-of-sight network.

A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal.
